Adaptive insertion policies for managing shared caches

Adaptive insertion policies for managing shared caches
Chip Multiprocessors (CMPs) allow different applications to concurrently execute on a single chip. When applications with differing demands for memory compete for a shared cache, the conventional LRU replacement policy can significantly degrade cache performance when the aggregate working set size is greater than the shared cache. In such cases, shared cache performance can be significantly improved by preserving the entire working set of applications that can co-exist in the cache and preserving some portion of the working set of the remaining applications. This paper investigates the use of adaptive insertion policies to manage shared caches. We show that directly extending the recently proposed dynamic insertion policy (DIP) is inadequate for shared caches since DIP is unaware of the characteristics of individual applications. We propose Thread-Aware Dynamic Insertion Policy (TADIP) that can take into account the memory requirements of each of the concurrently executing application...
